Abstract
A stitched sensor including a plurality of threads stitched to a textile in a stitch geometry is described. The plurality of threads includes a conductive thread, and the stitch geometry is configured such that an electrical property of the stitched sensor changes based on at least one of stretching, relaxation, or bending of the textile. Methods for forming a stitched sensor are also described.
Claims21
A stitched sensor comprising:
- a plurality of threads stitched to a textile in a stitch geometry, the plurality of threads comprising a conductive thread, wherein the stitch geometry is configured such that a resonance of the stitched sensor changes based on at least one of stretching and relaxation of the textile.
A method comprising:
- forming a stitched sensor by at least stitching a plurality of threads to a textile in a stitch geometry configured such that a resonance of the stitched sensor changes based on at least one of stretching and relaxation of the textile, the plurality of threads comprising a conductive thread.
A system comprising:
- a plurality of threads stitched to a textile in a stitch geometry, the plurality of threads comprising a conductive thread and one or more non-conductive threads, wherein the stitch geometry is configured such that a resonance of the conductive thread changes based on at least one of stretching and relaxation of the textile;
- and
- a sensing unit electrically coupled to the conductive thread in the stitch geometry and configured to sense the change in the resonance of the conductive thread.
